How to bind AuraTabView Items to ObservableCollection

[Shadow4walker]

it used to work in previous releases with some modified in the Data Template but now in "0.1.4.1" I got some exception System.ArgumentNullException: 'Value cannot be null. (Parameter 'target')'""
the Exception happened in Aura.UI.Controls.Generators.AuraTabItemContainerGenerator.CreateContainer

View

<AuraTabView TabStripPlacement="Left" Items="{Binding Peoples}">
    <AuraTabView.ItemTemplate>
        <DataTemplate>
            <StackPanel>
                <TextBlock Text="{Binding Name}" />
                <TextBlock Text="{Binding Age}" />
            </StackPanel>
        </DataTemplate>
    </AuraTabView.ItemTemplate>
</AuraTabView>

VM

    private protected ObservableCollection<Person> Peoples { get; } = new();

Person

public class Person {
    public Person(string name, string age) {
        Name = name;
        Age = age;
    }

    public string Name { get; }
    public string Age { get; }
}

Next I'm going to add support for Observable Collection, the current problem is there's not information about how to add it, I'm gonna ask it to the core devs (sorry for reply so late, I had problems with my internet connection)

[PieroCastillo]

wait... how are you using it? the items what are you using should implement IAuraTabItemTemplate

[Shadow4walker]

i've switched to Avalonia TabControl.
already tried with IAuraTabItemTemplate and the items just not displayed! can u give me example project with the worked solution

[PieroCastillo]

you're right, I remember with Avalonia 0.10.1 works fine... but now it's broken, I'm gonna work now to fix it

[PieroCastillo]

to display items it's ok, I'm gonna add a sample adding/deleting items, and using data Templates
https://github.com/PieroCastillo/Aura.UI/tree/master/MVVMSamples/AuraTabViewMVVMSample

[PieroCastillo]

it's done, now should work like the Avalonia sample
https://github.com/PieroCastillo/Aura.UI/blob/master/MVVMSamples/AuraTabViewMVVMSample/ViewModels/MainWindowViewModel.cs
https://github.com/PieroCastillo/Aura.UI/blob/master/MVVMSamples/AuraTabViewMVVMSample/Views/MainWindow.axaml

all working great thank you.
btw have you considered adding those two suggestions ScrollAble header Header with Remove item event it would be easier to just integrate this two suggestion by default within AuraTabView rather than edit template in each use

[PieroCastillo]

I think now I can close this issue :), also, could you open another issue specifing other details about the closing bug?

[Shadow4walker]

just wanted to tell you this issue still exist after your last update you may check is using your samples!

System.ArgumentNullException: 'Value cannot be null. (Parameter 'target')'

Fill the property "IsClosable"
